An Ofsted inspection of Trent Road Nursery in Grantham in November foundthe quality and standards of care and nursery education to be"inadequate" and the nursery has been issued a notice to improve bymid-May.
However, the association, which has the backing of parents using thenursery, says the report does not give an accurate picture and it willbe making a complaint to Ofsted.
The association set up five regional centres to support membersproviding childcare in disadvantaged areas and to be examples of goodpractice.
Chief executive Purnima Tanuku said: "They are still only 12 to 18months old and there are challenges to be overcome on the way."
An action plan to tackle the points raised in the inspection is alreadyin place.
